Thousands of styles are available to Zotero 1.5 users, and this is where to find new ones and make sure they're up to date. The Style Manager displays all the currently installed bibliographic styles and the date they were most recently updated. You can also add or delete styles from Zotero here. Style files can either be added manually using the + button, or automatically through the “Get additional styles…” link to http://zotero.org/styles. The - button deletes the selected style.
